Problems solved by technology

The magnetic deflection method requires high voltage and permanent magnets. Both the electrostatic analyzer method and the time-of-flight method require high voltage to form a strong electric field to accelerate electrons. Although these three detection methods can detect electrons, they need to introduce magnets into the detector. Or high-voltage electric field, resulting in a large volume and mass of the detector, it is difficult to meet the requirements of miniaturization and low power consumption of the detector in the space exploration activities

Description

technical field [0001] The invention relates to a detection device for space electrons, in particular to a detection device for 0.1-1 MeV electrons, and belongs to the field of detection of space charged particles. Background technique [0002] The traditional methods for detecting low-energy electrons in space are magnetic deflection method, electrostatic analyzer method and time-of-flight method. The magnetic deflection method requires high voltage and permanent magnets. Both the electrostatic analyzer method and the time-of-flight method require high voltage to form a strong electric field to accelerate electrons. Although these three detection methods can detect electrons, they need to introduce magnets into the detector. Or a high-voltage electric field, resulting in a large volume and mass of the detector, which is difficult to meet the requirements of miniaturization and low power consumption of the detector in the current aerospace exploration activities.
